f126ee26e7 the TrueType glyph loader is now much more paranoid, this avoids
unpleasant overwrites in the case of invalid glyph data (found in
the output of buggy font converters)

the computation of auto-hinted stem widths has been modified to
avoid certain color fringes in LCD-decimation rendering (a.k.a.
"ClearType")

warning.

1c2ef2b948 * src/type1/t1objs.c (T1_Face_Init): fixed a bug that crashed the
library when dealing with certain weird fonts (like "Stalingrad",
        in "sadn.pfb". This font has no full font name entry.. )

        * src/base/ftoutln.c, include/freetype/ftoutln.h: added the
        FT_Outline_Check API to check the consistency of outline data

        * src/base/ftobjs.c (FT_Load_Glyph): added a call to the new
        FT_Outline_Check to ensure that loaded glyphs are valid. This
        allows certain fonts like "tt1095m_.ttf" to be loaded even though
        it appears they contain really funky glyphs..

        there still is a bug there though.. !!

(ps_mask_table_merge, ps_hints_open, ps_hints_stem,
ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix
FT_ERROR messages.
* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as
`trace_pshalgo1'.

ae69e7dc7d * src/cff/cffgload.c: added a comment regarding "cntrmask" operator
* src/pshinter/pshrec.c: now ignores invalid "hintmask" and "cntrmask"
        operators (instead of returning an error). Glyph 2028 of the CFF font
        "MSung-Light-Acro" couldn't be rendered otherwise (it seems its
        charstring is buggy, though this requires more analysis)..

        the X and Y axis where inversed in the postscript hinter. this
        caused problem when displaying on non-square surfaces..

04658fcd81 * src/pshinter/pshglob.c (psh_globals_new): replaced a floating point
constant with a fixed-float equivalent. For some reason, some compilers
        aren't capable of directly computing a floating pointer constant casted
        to FT_Fixed, and will link a math library instead !!

        of making them part of a shared header (causing problems in "multi"
        builds)

(FT_Load_Glyph): "fixed" the bug that prevented embedded bitmaps from
        begin loaded when the auto-hinter is used.. This actually is a hack
        but will be enough until the internal re-design scheduled for
        FreeType 2.1

some of the exported functions should only be used by applications
        that need to implement custom cache types

        * src/truetype/ttgload.c: fixed a nasty bug that prevent composites
        from loading correctly. Believe it or not, this was due to an invalid
        macro definition !!

7ebd63726b * src/base/ftglyph.c (FT_Glyph_To_Bitmap): re-ordered code for debugging
purposes..


    * src/smooth/ftsmooth.c (ft_smooth_render): fixed a nasty hidden bug where
    outline shifting wasn't correctly undone after bitmap rasterization. this
    created problems with certain glyphs (like '"' of certain fonts..) and
    the cache system..

7b37145b63 First of all, a big thanks to Werner and Antoine for their latest work !!
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
      src/pshinter/pshalgo1.c (psh1_hint_table_init): removed compiler
      warnings

    * include/freetype/cache/*, src/cache/*: yet another massive rewrite of
    the caching sub-system, in order to both increase performance and allow
    simpler cache sub-classing. As an example, the code for the image and
    sbit caches is now much simpler

    I still need to update the documentation in www/freetype2/docs/cache.html
    to reflect the new design though..

Cleaning up of ChangeLog.

* docs/license.txt: s/X Windows/X Window System/.

* src/raster/ftraster.c: Fix definition condition of MEM_Set().
* src/smooth/ftgrays.c (M_Y): Change value to 192.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
Remove unused variable.
* src/cache/ftcimage.c (ftc_image_node_init,
ftc_image_node_compare): Remove unused variables.
* src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused
variable.
* src/raster/ftraster.c (MEM_Set): Move definition down to avoid
compiler warning.
* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
avoid compiler warnings.
* src/pcf/pcfread.c (tableNames): Use `const'.
(pcf_read_TOC): Change counter name to avoid compiler warning.
Use `const'.
* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
declaration.
* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
to avoid shadowing.
* src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.

782d522028 * src/pshinter/{pshalgo2.c, pshalgo1.c}: fixed stupid bug in sorting
routine that created nasty alignment artefacts.

        * src/pshinter/pshrec.c, tests/gview.c: debugging updates..

        * src/smooth/ftgrays.c: de-activated experimental gamme support,
        apparently, "optimal" gamma tables depend on the monitor type,
        resolution and general karma, so it's better to compute them outside
        of the rasterizer itself..

9f892b4ef1 * src/smooth/ftgrays.c: adding experimental "gamma" support. This
produces smoother glyphs at small sizes for very little cost

	* src/autohint/ahglyph.c, src/autohint/ahhint.c: various fixes to
	the auto-hinter. They merely improve the output of sans-serif fonts.
	Note that there are still problems with serifed fonts and composites
	(accented characters)

	* tests/gview.c: updated the debugging glyph viewer to show the
	hints generated by the "autohint" module
